UNITED STATES PATENT OFFIoa JOHN A. KIRGHNER, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN CRADLES.

Specification forming part of Letters Patent No. 186.737, dated January30, 1877; application filed March 6,1876.

To all wh0m t't may concern:

Be it known that I, JOHN A. KIRCHNER, of

Chicago, in the county of Cook and State of Illinois, have invented anImprovement in Cradles, of which the following is a specification:

The first part of my invention relates to an improvement in the mannerof putting together the .ends and sides of spindle-cradles, making aless expensive joint than the mortises and tenons heretofore used, andfully as strong, if not stronger.

The second part of my invention relates to an improvement in a platformto sustain the rockers of the cradle, and on which they vibrate, havingfor its object to enable the platform to adjust itself to inequalitiesin the floor, or to a covering thereof, which I accomplish by making thegirt which connects the two ends of the platform with ajoint.

The third part of my invention relates to the construction of a foldingwire frame, for supporting a mosquito-netting, which envelops thecradle, to protect the occupant from insect-bites.

Figure 1 is a perspective view. Fig. 2 is a crosssection at a: m. Fig. 3is a longitudinal section at y y.

In the dra ing, A A represent the ends and A A the sldes of aspindle-frame cradle. The ends and sides are composed of parallel upperand lower bars, connected by vertical spindles, in the ordinary mannerof constructing what is known in the trade as spindleframes, and the endframes are mortised to the corner-posts B, as is usual but the ends ofthe bars of the sides are doweled into the posts, and secured thereto bya screw, 01,, passing through each postand into the nearestspindle, asseen in Fig. 1, making a cheap but very strong joint. 0 O are therockers. D D are two light strips of wood, connected at the middle by agirt, D, on whose center a raised boss is worked, which is first severedand then bored through both parts, to receive a longitudinal pin, b, soas to permit the feet 0 under the ends of the strips D to accommodatethemselves to inequalities in the floor or its covering, and therebyafford a firm platform for the rockers of the cradle to oscillate upon.

To form a canopy-support, four wires are bent to a segment of a circleor other curve, and an end of each is inserted in a hole bored in thetop of'each post. The upper ends of these wiresE are hooked into a ring,0, over the center of the bed or cradle, and the support, when detached,can be folded on the said ring into a small compass.

What I claim as my invention is 1. A spindle-frame cradle, substantiallyas described, having its sides doweled to the corner-posts, and securedby a single woodscrew passing through each post into the nearestspindle, substantially'as shown and set forth.

2. The side strips D D, connected by the jointed girt D, substantiallyas described, for the purpose specified.

3. The canopy-frame for cradles described, consisting of the four curvedwires E, having their upper ends hooked into a central ring,

e,.when the said wires are adapted to be readily detached from thecradle and folded up together, substantially as described and shown.
